Give scientific reasons: Why are biogas plants more commonly found in rural areas?

(N/A) Biogas plants are more common in rural areas primarily because the raw materials required,such as animal dung and agricultural waste,are abundantly available there. In rural settings,livestock rearing is a major occupation,providing a continuous supply of dung. Additionally,biogas serves as an efficient,cost-effective,and eco-friendly source of energy for cooking and lighting in areas where access to commercial fuels like $LPG$ might be limited or expensive. Thus,the proximity to the source of raw materials and the practical utility make biogas plants highly beneficial in rural regions.
